Hi
I'm new in wicket. I tried to display a list of components, but I get the
following error:
WicketMessage: Unable to find component with id 'label' in [MarkupContainer
[Component id = link, page = com.myapp.wicket.HomePage, path =
0:mainNavigation:menu:0:link.BookmarkablePageLink, isVisible = true,
isVersioned = true]]. This means that you declared wicket:id=label in your
markup, but that you either did not add the component to your page at all,
or that the hierarchy does not match.
[markup =
file:/D:/workspace/NetBeansProjects/WicketTest/build/web/WEB-INF/classes/com/myapp/wicket/HeaderPanel.html
The html:
<html xmlns:wicket>
<body>
<wicket:panel>
<h1>Wicket Example</h1>
<p id="titleblock">
Start of Example Title Goes Here
</p>
<ul wicket:id="menu">
<li> </li>
</ul>
</wicket:panel>
</body>
</html>
The MarkupComponents are:

I have the following classes:
public class HeaderPanel{
public HeaderPanel(String componentName, String exampleTitle)
{
super(componentName);
add(new Label("exampleTitle", exampleTitle));
ArrayList<MenuModel> menu=new ArrayList<MenuModel>();
menu.add(new MenuModel("1", "HomePage", "First Page"));
menu.add(new MenuModel("2", "HomePage", "Second Page"));
menu.add(new MenuModel("3", "HomePage", "Third Page"));
MenuView view = new MenuView("menu", menu);
add(view);
}
}
public class MenuView extends ListView {
public MenuView(final String id) {
super(id);
}
public MenuView(final String id, final IModel model) {
super(id, model);
}
public MenuView(final String id, final List list) {
super(id, list);
}
@Override
protected void populateItem(ListItem item) {
final MenuModel element = (MenuModel) item.getModelObject();
Class clas;
try {
clas = Class.forName(element.getClas());
} catch (ClassNotFoundException ex) {
Logger.getLogger(MenuView.class.getName()).log(Level.WARNING,
null, ex);
clas=this.getApplication().getHomePage();
}
item.add(new Label("label", element.getLabel()));
item.add(new BookmarkablePageLink("link", clas,
new PageParameters("id=" + element.getId())));
}
}
public class MenuModel implements Serializable{
public String clas;
public String label;
public String id;
public MenuModel(String id, String clas, String label){
this.id=id;
this.clas=clas;
this.label=label;
}
public String getClas() {
return clas;
}
public void setClas(String clas) {
this.clas = clas;
}
public String getLabel() {
return label;
}
public void setLabel(String label) {
this.label = label;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
}
Any tips?
Thanks.
